Answer:

There is a direct relationship between the convection current, spreading of the seafloor and ocean basin formation.

During the time of divergent plate motion, two plates move in the opposite direction due to the convection current generating in the mantle layer, which forces the plates to move in the opposite way. This results in the formation of cracks on the seafloor, and with progressive motion, the seafloor spreading takes place, thereby forms a narrow type of valley, erupting the magma along with water. This, over some millions of years, turns into an ocean basin.

Thus, they are directly related to one another and are some of the major processes of plate tectonics.

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.

Dima020 [189]

Answer:

Pons.

Explanation:

Inside of our brainstem, there is a structure which is called the pons, which is present besides the medulla oblongata. The pons is a significant structure in the upper part of our brainstem. It controls breathing, communication between different parts of the brain, and as well as sensations such as hearing, taste, and balance.

Pons is that part of the brainstem which carries one-way communications that advise the cerebellum of voluntary motor activities initiated by the motor cortex.

The adrenal medulla is stimulated to release catecholamines during sympathetic autonomic nervous responses. True or False
forsale [732]

Answer:

True

Explanation:

Catecholamines refer to the hormones produced by the adrenal gland present on the upper side of the kidney. The catecholamine hormone includes the epinephrine, norepinephrine and the dopamine.

During stress conditions, the sympathetic division of the autonomic nervous system gets activated which leads to the release of the norepinephrine from the postganglionic neurons and the prolonged-release leads to the release of the adrenaline from the adrenal glands.

Thus, true is the correct answer.
